Tesla Model X VS Porsche Cayenne
Tesla Model X
Tesla Model X
Tesla - love the brand, or hate it - has done a lot for the automotive industry. It has made electric cars a talking point, something that competitor companies are finally acting on.
I spent a week in the 2018 Tesla Model X 75D, which happens to be the most affordable version of the US company’s crossover. Affordable? Well, that’s really going to depend on your salary.

Since the Porsche Cayenne turned the automotive world upside down in the early noughties, it has continued to evolve and has grown to become one of the brand's biggest sellers.
One size up from the mid-size Macan, it's problematic for hardcore Porsche-philes, but there's no doubting this five-seat SUV's success, or the fact that it helps keep the famous German sports car maker well and truly in the black.
And this is the new, third-generation version, with an all-new chassis, fresh engines, and a bunch of dynamic, safety and multimedia tech enhancements.

Tesla Model X7.9/10
The Tesla Model X in 75D specification offers a lot of technology for buyers who want to dip their well-heeled toe all the way into the electric mobility pool. There are more conservative and compelling options for customers who think plug-in hybrids are the first step, though - and if you’re not hellbent on a full EV, then we’d suggest maybe you have a bit of a look at what else is on offer.
Could you live with an electric car? Tell us what you think in the comments section below.
The Cayenne may be the Porsche of SUVs, but you can't have family car size and practicality without a few concessions.
It's fast, beautifully built, and engineered with a special eye for detail, and the well specced Cayenne S is the pick of the bunch for performance and value.
But it's worth remembering the SUV bit. This Porsche is more everyday enjoyment than track day excitement.
Is the Cayenne your kind of premium family truckster? Tell us in the comments below.
Tesla Model X
That’s just me, and like everyone I’m entitled to my opinion. I know there are people out there who absolutely love the exterior design of the Model X. If you’re one of them, let me know - I have a great optometrist I can refer you to.
Seriously, though - the Falcon Wing rear doors are design overkill. No-one needs back doors that open up like that, and the amount of compromise that has been built into the rest of the vehicle’s design because of them is noticeable - I couldn’t open the back door on the driver’s side of my test vehicle at home because I was apparently parked too close to the bin - the axis angle at the top of the door limited how far the bottom of the door would open. I can’t understate how rubbish this would be if your home parking space was tight.
Plus this example (and the few I’ve seen/sat in prior) had some issues with quality, like mismatched panel gaps around the doors and hatch. Take a look at our photos to see for yourself.
The massive windscreen stretches to above the front occupants’ heads, and it’s tinted to try and eliminate sunlight overhead - and Tesla has added a mesh shield visor that you can slot in, and although it is welcome, it’s flimsy, and would be easy to knock down when you’re moving the actual (magnetised) sun visors.
Now, as a piece of design, the glass is great - but other vehicles with big glass have smart solutions integrated into them, like the Citroen Grand C4 Picasso, with its pull-down blinds and proper sunvisors.
I guess it’s a bit like an architecturally designed house that’s really cool the first time you see it, but really hard to live with. The sunvisors are very thin, and it’s difficult to position them to block the sunlight, especially driving in an easterly direction in the morning (as I do) and a westerly direction in the afternoon (yep, that’s me). Plus, the visors don’t have vanity mirrors - a disaster for makeup artists on the move.
Things I like? The LED headlights and LED daytime running lights are exceptionally good, and the wheels that this model comes with as standard are nice, even if they look a bit dwarfed by the bulk of this slab-sided high-rider.
And if you’ve ever wondered why every Tesla Model X has its rear spoiler in the ‘up’ position at all times, it’s because it’s a fixed spoiler.
The design is new yet familiar. Longer (+63mm), wider (+44mm), lower to the ground, and lower overall (-9mm), yet the wheelbase is unchanged at just under 2.9m.
All models feature LED headlights, and the Cayenne and Cayenne S are identified by their silver grille slats, with the Turbo featuring matt and high-gloss black surfaces plus larger air intakes at the front.
Car-spotters will also notice narrower side windows with a sharper decline at rear (Porsche calls it the Flyline) and the C-pillars tilting forward for a racier look.
A full width horizontal light strip across the tail sits under a clear covering above a three-dimensional version of the Porsche logo.
And wheels now range in size from 19-inch on the Cayenne, 20-inch on the Cayenne S, to 21s on the Turbo, plus optional 22s, presumably for those who drive on billiard table smooth freeways at all times.
And the Cayenne now features staggered or mixed tyres for the first time, that is fatter rubber on the back than the front.
Inside, the biggest change is the adoption of the Panamera's 'Advanced Cockpit', with the central tachometer in the iconic five-gauge instrument cluster flanked by twin 7.0-inch screens to create a blended analogue/digital version of the classic Porsche five dial layout.
Plus, there's the sleek 12.3-inch screen in the centre running everything from nav and vehicle settings to audio control and phone calls, through touch and voice.
Again, it's a direct lift from the Panamera, and the screen layout can be customised to personal preference, with Apple CarPlay standard (but no Android Auto).
Tesla Model X
There are good and bad elements to the interior design.
The ingress and egress to the third row is better than some SUVs because the floor is so low - meaning it’s easy to step in and out of - but also worse than some SUVs because the shape of the opening is odd.
Space in the third row is better left for children or small adults with limited legroom and headroom, and while there are vents back there the vision for occupants is limited; the seats are low, and if you’re little you won’t be seeing much.
If the Model X had electric sliding doors rather than the Falcon Wing doors, it would be more practical. If you park in a tight space, a sliding door allows you to still get out, but these doors won’t even open all the way if the sensors detect they are unable to. That’s annoying, because this is a really wide vehicle, and some parking lots seem to be making spaces smaller and smaller.
Anyway, I’m not going to win the battle of sliding vs gullwing doors here, am I?
The boot space is good - with seven seats up you can make use of the hidden compartment below the floor, and with five seats in use the cargo capacity is very good, too. Then there’s the front trunk - no engine means you get bonus storage, and Tesla claims total cargo capacity for the Model X is 2492 litres for the five-seat version.
You can get a five-seat, six-seat or seven-seat version of the Model X. This vehicle used to have electric sliding and folding second-row seats, but now there’s a push-button system, which still uses some form of electrical pulse to unlock the rails below the seats. While it’s quicker than electric would have been, it's not as simple as, say, a lever like you’d find in the Mazda CX-9.
For outboard second-row occupants the space is okay - I set the driver’s seat in my position and had enough legroom and headroom to be comfortable in the second row. But anyone in the third row would have been squished. The middle-row middle-seat of our test car was less than impressive, with little head room and not much width available.
Storage is well sorted up front, with two large centre bottle holders, plus bottle holders in the front doors (none in the rear, for obvious reasons) and a pair of cupholders up front. The storage situation is poor for those in the back: there are no cup receptacles at all for the second row, but there are dual USB ports. In the third row there are two cup holders, and all three rows have air vents.
Practicality highlights are more storage around the cabin, and a slide and recline adjustable rear seat.
Up front, the glove box is cooled, there are storage compartments under both seats, plus two cupholders, decent bottle holders in the doors, a 12-volt outlet (under the glove box), as well as two USB charge and connectivity ports in a generous console storage box.
Jump in the back and you'll find door bins with space for bottles, map pockets on the front seat backrests, a pair of cupholders in the fold-down centre armrest, plus two USB charge ports and a 12-volt socket in the centre console.
The rear seat's tilt and slide party trick means there's plenty of leg and headroom in the rearmost, fully reclined position. But tweak a lever on the side and a pull handle under the cushion and you can move forward (in stages) to liberate as much as 100 litres of extra cargo space over the outgoing model, while maintaining seating for five (three without legs in the extreme forward position).
Porsche's official description of the rear bench offering “two comfortable seats outside left and right and one centre seat” accurately sums up the relatively squeezy plight of the centre rear passenger.
Cargo capacity is 770 litres with the 40/20/40 rear seat upright, and a handy 1710 with it folded forward. There are four tie-down anchor points, plus a netted storage area on the passenger side, two lights and yet another 12-volt power point.
An auto tailgate is standard on all models, and a 20-inch collapsible spare (with inflator kit) sits under the rear floor.
If towing is your thing the Cayenne's weight ceiling is 3.5-tonne for a braked trailer, and 750kg unbraked. Porsche's 'Trailer Stability Management' system is standard.
Price and features
Tesla Model X
How much is a Tesla Model X? It isn’t cheap, that’s for sure. But this 75D version is currently the lowest cost model in the brand’s SUV price range.
The price of the 75D kicks off at $125,000 plus on-road costs, or $142,475 drive away - but where you live will determine the drive-away price, because different states and territories have different stamp-duty implications for electric cars. ACT buyers ($142,475 RRP) get a much better dealer than those in WA ($151,174 RRP), for instance.
Pricing jumps significantly if you want the more performance-focused 100D, which also gains extra battery range (prices from $173,805 drive away) or the flagship P100D we tested recently (from $247,385). That’s right - the Model X we have is more than a hundred grand cheaper than the top model.
The Model X comes pretty well equipped from the factory, with a 17.0-inch touchscreen media display featuring Google Maps sat nav with realtime traffic updates, Bluetooth phone and audio streaming, digital DAB radio and integrated TuneIn app connectivity. There's no Apple CarPlay or Android Auto, though.
Other standard items include keyless entry and a self-opening (and self-closing) driver’s door, an electric tailgate, interior ambient lighting, air suspension with ride height adjustment, auto headlights with auto high-beam lights, LED fog lights, power adjustable and auto-folding heated auto-dimming side mirrors. You get 20-inch wheels as standard, but there's no spare wheel - tyre-pressure monitoring is fitted, and if you get a flat, you'll need to call roadside assist.
There are standard heated seats for every occupant and there’s a heated steering wheel, heated windscreen washer nozzles to help defrost if you’re heading to the snow, and if you download the app you can adjust the temperature inside the car remotely - cold starts on winter mornings are a thing of the past.
The app also allows you to monitor the vehicle’s state of charge, enable someone else to drive your car without the keys present (you just have to input your password in the app), and you can unlock/lock the car and/or open the front or rear trunks, start it, honk the horn, flash the lights, set the speed limit or enable ‘valet mode’, so those pesky parking attendants don’t go using all your juice doing speedy starts.
How many seats in the Tesla Model X? Well, you can have it with five seats as standard, six seats for an additional $8300 (with or without a rear centre console) or seven seats for $4100.
Other options fitted to our vehicle included grey painted 20-inch wheels (as opposed to the silver rims you get on the standard version: $2800), the White Premium interior pack ($4600) and the carbon-fibre upgrade ($350), Deep Blue metallic paint ($2100) and the Enhanced Autopilot system ($6900).
So, in the end, our affordable Model X cost more than $175,000 on the road… ouch. You can get any one of a number of petrol or diesel SUVs from competitor luxury brands for less money, and plenty with plug-in practicality, too.
If you want a luxury plug-in hybrid SUV, consider the Volvo XC90 T8 plug-in hybrid from $122,900, or a Porsche Cayenne e-Hybrid from $135,600, or the Mercedes-Benz GLE500e for $129,500, or the Audi Q7 e-tron from $139,900, or the BMW X5 xDrive40e from $124,990.
Admittedly, none are full EVs, but the Audi e-tron model is due next year…
You should also be aware of the wait time associated with a Tesla - the vehicles are built to personal specifications, so unless you’re buying a second-hand car, or a demo from the company’s (small!) stock list, it could mean a wait time of about three months. The Tesla web configurator allows you to get an idea of approximate delivery dates. Some buyers will take that with a grain of salt, though, given customers have waited about two years for their Model 3s.
If you don’t want to wear the depreciation, you could consider a used car - there are pre-owned Model X and Model S examples on Tesla’s website.
There are three models offered initially, starting with the Cayenne, powered by a 3.0-litre single turbo-petrol V6 for $116,300 before on-road costs. Then the 2.9-litre V6 Cayenne S adds a second turbo and around $40k to the price tag, coming in at $155,100.
The powerhouse Turbo tops the line-up with a 4.0-litre twin-turbo petrol V8 under the bonnet, and cost of entry sitting at $239,400.
Not a diesel in sight (for Australia) for the time being, with an E-Hybrid variant due here closer to the end of this year.
As you'd expect in this part of the market the standard equipment list is solid, with the Cayenne featuring partial leather trim, cruise control, LED headlights, daytime running lights and tail-lights, rain-sensing wipers, dual-zone climate control, privacy glass, front seats with 14-way electric adjustment and memory settings, remote central locking with 'Keyless Go', the twin digital instrument displays, multi-function sports steering wheel (with gearshift paddles), auto tailgate, 'Porsche Active Suspension Management (PASM - with adaptive dampers), 19-inch alloy wheels, and 'Porsche Communication Management' (PCM) with the 12.3-inch screen controlling nav, phone and audio (10-speaker, 150 watt and digital radio).
As well as it's more powerful twin-turbo V6 engine, the Cayenne S adds 'Adaptive PASM' (with air suspension), 20-inch alloy rims, twin dual-tube tailpipes, dynamic (directional) LED headlights, a dual-pane panoramic sunroof, heated front seats, pedal faces in stainless steel, a 710-watt Bose 'Surround Sound System' with 14 speakers (including subwoofer), and metallic paint in any one of seven colours.
Then the Cayenne Turbo piles on the power and luxury with the twin-turbo V8 joined by 21-inch alloys (in dark titanium with highly polished surfaces) including wheel arch extensions in the exterior colour, 'Porsche Active Aero' (with adaptive roof spoiler), scrolling LED indicators, 'LED Matrix' headlights, 'smooth finish' leather upholstery, 18-way electronically-adjustable 'Adaptive Sports' front seats with unique trim and fatter side bolsters, front and rear seat heating (and ventilated/cooled front seats), exterior mirrors with kerb-view parking aid, a heated steering wheel, 'cross-brushed' aluminium interior highlights, and Alcantara roof lining (cloth on base and S).
If you're ready to stump up the big bucks, that's a heap of fruit to go with this car's comfort and performance potential.
Engine & trans
Tesla Model X
Not so much an engine, but a 75kWh battery pack with a claimed 210km/h top speed and a 0-100 claim of 5.2 seconds. The claimed driving range for the Tesla Model X 75D is 417 kilometres. You don’t have gears to play with - Tesla’s run a single-speed transaxle, but the stalk to control it is sourced from Mercedes-Benz.
Remember, this isn’t the ‘fast’ Model X. But the D in the name signifies that it has Tesla’s dual-motor all-wheel drive system, ensuring excellent traction for super-quick acceleration.
As you might expect, stepping up to the Model X 100D with a 100kWh battery pack and dual motors increases the performance considerably (0-100: 4.9sec; 250km/h top speed), and also adds more electric driving range (565km claimed).
Go all out on the P100D and apparently your Model X will do 0-100 in 3.1sec, thanks to the addition of Ludicrous Mode, but the battery range drops away slightly (542km). Tesla says it’s the quickest SUV in history - and even in 75D guise it’s pretty rapid.
Every Tesla Model X is prepped for towing, too - the towing capacity is rated at 750kg for an un-braked trailer, and 2250kg for a braked trailer. The tare mass for the Model X is 2352 kilograms.
The new car's engines are lifted from the Panamera, and not only feature more power than the outgoing Cayenne, but Porsche claims improved fuel economy and lower emissions.
All feature an alloy block and heads, the Cayenne's 3.0-litre, single turbo V6 delivering 250kW from 5300-6400rpm, and 450Nm from just 1340rpm all the way to 5300rpm.
This 'base' engine features direct fuel-injection, 'VarioCam Plus' (variable cam control on the inlet and outlet side, and valve-lift adjustment on the inlet side), as well as the turbo located in the engine's vee to help minimise lag.
The Cayenne S's 2.9-litre V6 adds a second turbo to deliver 324kW from 5700-6600rpm, and 550Nm between 1800rpm and 5500rpm. It's shorter stroke design helps lift the rev ceiling by 300rpm (to 6800rpm).
Then the Cayenne Turbo adds two more cylinders to pump out no less than 404kW (542hp) across a narrow plateau from 5750-6000rpm, and 770Nm between 1960rpm and 4500rpm. The V8 also locates the turbos in the 'hot vee', but drops back to 'VarioCam' (variable cam control on the inlet and outlet side) without valve-lift adjustment on the inlet side.
All models now feature an eight-speed 'shift-by-wire' 'Tiptronic S' auto transmission, with drive going to all four wheels courtesy of Porsche's Active Traction Management system. The gear set in the Turbo (including the final drive) is slightly taller, although the seventh and eighth ratios are overdriven on all models to maximise fuel economy.
Claimed 0-100km/h times (with optional Sport Chrono package numbers in brackets) are: Cayenne – 6.2sec (5.9s), Cayenne S – 5.2sec (4.9s), Cayenne Turbo - 4.1sec (3.9s).
And if you have a very long driveway, leading up to your (presumably) very large house, you'll be pleased to know maximum velocity for the Cayenne is 245km/h, rising to 265km/h for the S, and a stonking 286km/h for the Turbo.
Tesla Model X
None. Well, it consumes electricity, so if you’re getting your energy from green sources, you can drive carbon-neutral in the Model X.
As mentioned above, a full charge will get a claimed 417km. On test, we picked the Model X up will a full ‘tank’, and got it down to 7 per cent remaining over about 400km - so the claim is pretty truthful.
But yes, I got range anxiety, and yes, I Googled “how long does it take to charge a Tesla Model X?”
The charge time really depends where you do it. If you go to a Supercharger - Tesla’s network of high-amperage, big power output (up to 120kW per car) fast-charge stations, you can expect to get to 80 per cent from empty in about 45 minutes, or all the way to full in a bit more than an hour. It used to be free to recharge at Superchargers, then increased demand saw Tesla introduce a pay-per-use fee, but all Tesla owners get 400kWh of credits to use every year.
If you charge at a destination charger like I did, the results are far, far worse. I parked up at the Supercheap Auto Penrith charge point, which is capable of up to 22kW’ of power output at just 6 amps, and left the car there for a full business day. It started at 7 per cent, and when I got back, it was at 53 per cent.
These destination chargers make sense if you’re going away for the weekend and can leave the car plugged in while you relax at the resort, but you need to know they’re not Superchargers. The network of Superchargers is getting bigger and bigger, and theoretically you can drive from Adelaide to Brisbane using them now.
Every Tesla comes with a wall connector for you to install at home, but there are options for how powerful it can be, and can be “tailored to your home’s supply” - be it three-phase or single-phase. On single-phase power, the output can be 16, 20, 24 or 32 amps. According to Tesla’s Australian site, 16-amp three-phase power will charge at a rate of about 50km per hour, while at 24-amp you could see 80km per hour added (meaning about five hours to fully charge in this spec).
If you want the specs and figures, our Model X had used 136kWh over the total 507km of its life to date, at an average of 269Wh/km. So, if your energy company bills you $0.22 per kWh, it’ll cost you about $30 to do 500km. Not exactly cheap, but you’re not buying a Tesla to save money - and if you have a good home solar array setup, you should be able to run your house and your car at no extra cost.
And Tesla has a deal with AGL so you can charge your car for $1 per day. That means you can theoretically fill it up every evening with energy, and you won’t spend more than $365 for a year of driving.
So, the Model X gets a 10 out of 10 for fuel consumption. But if these ratings included a ‘time-consumption’ figure, it would be a lot less!
Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle ranges from 9.2L/100 km for the Cayenne (emitting 209g/km of C02 in the process), to 9.4L/100 km for the Cayenne S (213g/km), and 11.9L/100 km for the Cayenne Turbo (272g/km).
All models feature auto start-stop (with coasting), your only fuel option is 98 RON premium unleaded, and you'll need 90 litres of it to fill the tank.
Tesla Model X
With two electric motors and a huge bank of lithium-ion batteries to work with, the acceleration of the Model X is impressive. Throttle response is good, and from a standing start you will still impress your friends - even if you don’t buy the Ludicrous version.
On-the-move acceleration is good, too, because there’s no transmission or turbo lag as you’d find in any of the Model X’s natural competitors. It’s quick, and even if you’re driving it sedately it’s nice to know there’s power in reserve if you need it.
It is a heavy vehicle, but the weight is mainly down low, with Tesla’s skateboard battery platform between the axles making it feel suctioned to the ground. The 20-inch rims with Michelin rubber (255/45 front, 275/45 rear) offer tremendous grip, and the traction is better than you’d likely find in other, more traditional SUVs.
The air suspension does a decent job of cosseting those in the cabin from the road surface below, provided it’s smooth. Some shortcomings are noticeable over sharp edges, such as speed humps, where it can feel a bit stiff-legged, and there’s the typical side-to-side wallow you see from airbag suspension.
The electric steering system offers nice accuracy and response, with a linear weighting that means it’s easy to turn the wheel, whether you’re pushing it through corners or simply trying to park it at the shops.
Some things that could be better? The visibility is the biggest issue, for me. This is a big vehicle, and the rear-view mirror is tiny, as is the vision it offers. If you have people in the third row, there’s almost no point even trying to use it.
I used the Enhanced Autopilot system on my commute, and it worked very well, you just need to ensure there’s some pressure on the steering wheel. This isn’t a full autopilot system, and shouldn’t be treated as such: you need to maintain control of the car and be conscious of your surroundings, because it isn’t perfect, and if you disobey its commands to ‘keep light pressure on the wheel’, it will disable for the rest of your drive.
I was surprised there wasn’t a surround-view camera system fitted to this car, especially given there are so many driving-system cameras and radars fitted.
Other concerns? The creaking and groaning of the body and the rubbers as you turn corners, particularly over offset low-speed bends in car parks and the like. This isn’t the sort of thing you hear in the established luxury SUVs.
And of course, if you’re getting a Tesla, spend the money and get the best home-charging solution you can. It’ll put your mind at ease. Or just move close to a Supercharger.
The new Cayenne sits on the VW Group MLB Evo platform, which also underpins the Audi Q7, Bentley Bentayga, Lamborghini Urus, and the soon-to-arrive new generation VW Touareg.
It uses a lot of aluminium and lightweight high-strength steel which, in concert with the alloy body panels, makes the car not only stiffer, but lighter by up to 65kg.
We've driven each model over a two-day launch program in The Barossa Valley in South Australia, and can confirm the base Cayenne is quick, the S is properly fast, and the Turbo is ballistic.
The transmission is a conventional eight-speed auto, rather than Porsche's PDK dual-clutch, and shifts are quick but smooth in normal mode, transitioning to a sharper, even more precise response in Sport or Sport Plus.
Porsche stands proudly on its reputation as a great sports car maker and says the Cayenne fits easily into that context. But let's face it, this is a two tonne SUV, and while it's dynamically outstanding, it's no 911.
All models feature multi-link suspension front and rear including active dampers, with varying levels of suspension sophistication as you walk up the range, to three chamber air suspension on the Turbo.
On quick twisting B-roads it's fast, in the case of the Turbo, bloody fast. It grips hard thanks to fat Z-rated rubber and active drive distribution makes sure it puts its power down perfectly. But no matter how sophisticated the suspension tech, it still feels large and relatively top heavy.
The electromechanical steering is light, and while it's accurate, no matter which mode you're in road feel is modest.
Not surprisingly, the ride firms up in tune with sportier drive modes, but in Comfort, even the Turbo on 21-inch rims, soaked up the irregularities of at times choppy rural roads with surprising ease.
Given the car's mass and performance potential braking is an understandable priority, with even the base model featuring big ventilated rotors all around with four piston calipers at the front and two at the back.
The S ups that to six piston front and four at the rear, while the Turbo debuts Porsche's 'Surface Coated Brake' a Tungsten-Carbide coating on the discs and special pads for longer life and less dust. Of course, the front calipers are 10-piston with four at the rear (and they're white just to prove brake dust isn't a problem).
In typical Aussie conditions these monster brakes are like cracking a walnut with a sledgehammer. Stopping power (on all models) is immense, and pedal feel is agreeably progressive.
We also headed off-road through rutted dirt and rocky climbs, and with five drive and chassis modes at its disposal the Cayenne ate it up.
The different off-highway modes ('Gravel', 'Mud' and 'Rock') will lock and unlock the centre and rear diff as required and the adjustable hill descent control made crawling down steep slopes a breeze. You can even option up an 'Offroad Package' bringing extra protection for vital components, as well as off-road specific info in the PCM and a compass display on the dash.
If you need to think about the dips and climbs on your country retreat, or maybe just the pitch of your driveway, the Cayenne and Cayenne S's approach and (with the Turbo in brackets) is 25.2degrees (23.3), ramp over is 18.7degrees (16.7), departure is 22.1degrees (20.4), ground clearance measures 210mm (190mm), and fording depth is 500mm (475mm).
Tesla Model X
There is no ANCAP or Euro NCAP crash test rating for the Tesla Model X, but the vehicle scored extremely well in NHTSA testing the US, scoring the highest rating in history for any SUV.
The Model X sold in Australia gets an array of safety gear, including a collision-warning system and autonomous emergency braking, a reversing camera and parking sensors front and rear, plus there are airbags for first and second row occupants, but no curtain airbag coverage for those in the rear row.
Models fitted with Enhanced Autopilot (which will be all of them, we reckon) have four cameras and 12 ultrasonic sensors that monitor the road and the vehicle’s surroundings. Engaging autopilot means the car works to maintain the vehicle’s line in a lane of traffic, it can change lanes at the tap of the indicator stalk (thus letting the car do the blind-spot checking for you), and it can adjust speed to mimic other road users. It slows to a complete stop, and will take off again when things get moving once more.
In better news for parents, there are ISOFIX child seat anchor points in four of the five rear seats, plus top-tether attachments for all five rear seats - so baby capsules shouldn’t be an issue.
Active safety systems include the usual suspects like ABS, ESC, and traction control (ASR), with the addition of other features under the 'Porsche Stability Management' umbrella, including ABD (torque vectoring by braking), and MSR (prevents slip on the drive wheels produced under engine braking)
There's also AEB (although the Porsche system doesn't bring the car to a complete stop), 'Park Assist' (front and rear) including 'Surround View', 'Lane Keeping Assist', 'Lane Change Assist', and tyre pressure monitoring.
But if all else fails passive features include an active bonnet (activated by pedestrians, cyclists, etc detected by the front camera), driver and front passenger airbag, knee airbags for the driver and front passenger, front side airbags, rear side airbags and full-length curtain bags.
There are three top tether points across the back seat with ISOFIX anchors on the two outer positions. ANCAP hasn't assessed the third generation Cayenne so far, but its Euro NCAP affiliate awarded a left-hand drive, 3.0-litre diesel model a maximum five stars in 2017.
Tesla Model X
Tesla offers a strong eight-year/160,000km warranty for the vehicle, and the warranty extends to unlimited kilometres for the drivetrain.
The company asks owners to service their Model X (or Model S) every 12 months or 20,000km, whichever occurs soonest. And with few moving parts, you’d expect service costs to be pretty low - however, there is no capped-price-servicing plan.
